SHEAR-BOW.

SPECIFICATION forming part of Letters Patent No. 529,513, dated November20, 1894. Applicationfiled March 31,1894. Serial No. 505,855. (Nomodel.)

T0 all whom it 71m1/ cmwern:

Be it known that we, DWIGHT \VHEELER and DAVID C. WHEELER, citizens ofthe United States, residing at Bridgeport, in the county of Fairfieldand State of Connecticut, have invented certain new and usefulImprovements in Shear-Bows; and we do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

Our invention relates to the manufacture of soissors and shears and hasfor its object to provide the bows of scissors and shears with a liningof leather, felt, cloth or any suitable material, which will give to theshears a neat and attractive finish, will make them pleasant to use asit will protect the fingers against chafing and which will lessen thecost of production as it will dispense with the Operations of finishingand plating the inner sides of the bows.

With these ends in view our invention consists in an improved shear bowand in the method of making the same which we will now describereferring by numbers to the accompanying drawings forming part of thisspecification, in which- Figure 1 is an elevation of a pair of shearsembodying our novel invention, a portion of the lining being broken awayto show the rough surface underneath; Figs. 2 and 3, sections of one ofthe bows and the fiexible die by which the lining is attached in place,Fig. 2 showing the die inserted in the bow but remaining in its normalposition and Fig. 3 showing the die compressed so as to clamp the liningfirmly in position in the bow, and Figs. 4 and 5 are views similar toFig. 3 show` ing the die made in two parts.

1 denotes the bows of shears the inner sides of which are leftunfinished as at 2, and 3 denotes a lining of any suitable material forexample leather, felt or cloth which is attached to the inner sides ofthe bows in the manner which we will now describe. The inner sides ofthe bows are left rough just as they come from the molds in casting sothat the expense of finishing the inner sides of the bows and afterwardof japanning or plating them is avoided. The inner sides of the bows arethen prepared by placing thereon a solution of adhesive gu ms, thesolution used being somewhat in the nature of a varnish, shellacpredomiuating. The special compound of gums is not of the essence of ourinvention, it being simply necessary that the solution be stronglyadhesive and capable of being firmly set by the application of heat soas to attac-h the linings in place with perfect firmness, making itpractically impossible to remove them in ordinary use. The liningdenoted by 3 is cut in the form of a ring and the ends secured togetherby sewing or stitching so as to make the ring of required size. The bowand the ring are then placed over an expanding or tlexible die denotedby 4. This die is in fact a block of rubber which is preferably providedwith a groove 5 in which the bow and ring are loosely seated, the diebeing ordinarily shaped substantially as shown in Fig. 2, diagonallyopposite ends being cut away sufficiently so that the die may be readilyinserted, one end being first placed in position and then the other.After placing the die in position it is compressed as in Figs. 8, 4, and5 so as to press the lining firmly into place on the innerside and edgesof the bow in which position, i. e., the position shown in Figs. 3, Li;and 5, the die is clamped by any suitable means. The die, lining and boware then placed in an oven and baked. The exact heat to which the ovenmust be raised or the exact length of time taken in the baking are notof the essence of our invention and may be varied to suit the specialadhesive com-` pound used or the judgment of the manufacturer. As aperfectly practical temperature and time we would say raise thetemperature to 300 Fahrenheit and allow the bows to bake for thirtyminutes, it being simply necessary that the heat be sufficient tothoroughly melt the guins and that it be continued for a sufficientlength of time to dry out the moisture and cause thorough adhesion tothe rough metal of the bow. After the baking operation the edges of thelinings are ti'immed in any suitable man'x'ner which finishes them readyfot' u'se.

Having thus described our invent'ion, we e1aim The method of liningsheai' bows herein described the same eonsisting in appiying a solutionof adhesive gums to the roug'fh inner side of the bow, prepai'ing thelining in the form of a ring, then placing the bow and the ring over anexpanding die, then'expanding the die so that the lining will conform tothe Outline of the bow in which position it is retained in any suitabletnnne-i', and finally bking' the Iin'ing tot'he' how' while it is heid t5 in position by the die. i

In testimonywhereof we affix oursignatures in presenee of two witnesses.
